here for you, Arch Design Tool.

you can tile your arch as how you want now.

Arch Design Tool, consisted of two node groups : arch drawing and mortar drawing.

the only things that you have to are to change parameters and, if you like to have more complex patterns, duplicate the arch node group.

i share 4 different example versions of arch tools for you to discover how the repetition of the node group works and varies the results.

the rest is just up to you.

enjoy.
